TECHNICAL FIELD

Embodiments disclosed herein relate to a secure cloud browser with extended policy control and third party analysis integration.

BACKGROUND

When a user navigates an unsecure network such as the World Wide Web (e.g., the Internet), the user may be exposed to a variety of data security risks. For example, a webpage visited by the user may undesirably identify location and/or identity information of the user, which may be used maliciously by the webpage. Accordingly, a need exists for increased web browsing security.

DETAILED DESCRIPTION Introduction

Embodiments described herein may be directed to systems, methods, apparatuses, devices, computer program products, computer-executable instructions, and/or applications for securely and anonymously accessing web resources and customizable attribution of identity. In accordance with the present disclosure, a user may inspect and analyze a webpage as well as the underlying source code from an “arm's length” using a secure analysis application to prevent exposure on the user's local machine. The secure analysis application may provide increased flexibility in masking and/or modifying the user's digital persona to external websites.

Further in accordance with the present disclosure, the secure analysis application may be integrated with a translation service to translate textual web content without the web content provider being alerted that a translation is taking place. The secure analysis application may additionally or alternatively be integrated with a temporal and/or persistent cloud-based storage platform that allows data to be stored between sessions and selectively shared among users in an organization.

As used herein the term “cloud browser” may refer collectively to at least one of a secure analysis application, a secure web container, an egress node, a web server, a cloud-based storage system, and/or any other computing device. It is understood that the cloud browser described herein may include multiple cloud browsers, multiple secure analysis applications, multiple secure web containers, multiple egress nodes, multiple web servers, multiple cloud-based storage systems, multiple computing environments described herein, and/or the like. In some embodiments, a cloud browser may be executed by a private cloud (e.g. within an organization firewall) and/or public cloud (e.g. by a computing resource, such as a server farm, possibly shared with a unrelated entities and/or performing unrelated tasks).

System Operation

Referring now to the Figures, FIG. 1A shows an exemplary system 100 for providing a user 102 with a secure and anonymous web browsing experience as described herein. Using a secure analysis application 104 (e.g., a web browser application) running on a user device 106, the user 102 may initiate a secure web browsing session to access web content via a network (e.g., the Internet). In some embodiments, initiating a secure web browsing session includes establishing a communication connection between the user device 106 and one or more other devices based at least in part on one or more wireless and/or wired communication protocols as described herein.

During the secure web browsing session and via the secure analysis application 104, the user 102 may select one or more secure web containers 108 (e.g., separate web browsers each having a different location (e.g., Internet Protocol (IP) address) and/or identity (e.g., device identification number) than the secure analysis application 104 and/or the user device 106 in the network) through which the web content may be accessed by the user 102. In this way, the one or more secure web containers 108 may serve as separate and secure proxy web browsers for providing the user 202 with the web content while insulating the secure analysis application 104 and/or the user device 106 (and thus the user 102) from unwanted location and/or identity exposure in the network. The secure analysis application 104 and/or the user device 106 (and thus the user 102) may be partially insulated from the web content (e.g. only certain types of web content are prevented from passing through directly to the user device), substantially insulated from the web content (e.g. certain file and/or web content types and/or “exceptions” may be passed through to user device), and/or fully insulated from the web content (e.g. no file type and/or web content type is allowed to pass through to the user device without screening and/or modification).

Additionally, during the secure web browsing session, the user 102 may select one or more egress nodes 110 (e.g., router outputs through which an IP data packet (e.g., the web content) enters a public network such as the Internet (e.g., the network)) through which the web content, as well as any other data transmitted and/or received during the secure web browsing session, is to be routed. The one or more egress nodes 110 may each have a different location and/or identity than the secure analysis application 104, the user device 106, and/or the one or more secure web containers 108 in the network. As such, selecting the one or more egress nodes 110 through which web content is to be routed provides an additional layer of security and anonymity.

For example, when the user 102 accesses the web content via the secure analysis application 104, a selected secure web container 108 (e.g., secure web container 1 of FIG. 1A), and a selected egress node 110 (e.g., egress node 1 of FIG. 1A), only the identity and/or the location of the selected egress node 110 may be exposed in the network (as opposed to the location and/or the identity of the secure analysis application 104, the user device 106, and/or the selected secure web container 108). By not sharing the location and/or the identity of the secure analysis application 104, the user device 106, and/or the selected secure web container 108 and instead only sharing the location and/or the identity of the selected egress node 110, the location and/or the identity of the user 102 may be effectively protected during the secure web browsing session.

As illustrated in FIG. 1A, the web content may be accessed from one or more web servers 112, which are configured to receive web content requests from the one or more egress nodes 110. However, even though the user 102 may initiate a web content request via the secure analysis application on the user device 206 and using the one or more secure web containers 108, only the location and/or the identity of the one or more egress nodes 110 (and not the locations and/or identities of the secure analysis application 104, the user device 106, and/or the one or more secure web containers 108) may be identified by the one or more web servers 112 upon receipt of the web content request.

Because the location and/or the identity of the one or more secure web containers 108 (as well as the secure analysis application 204 and the user device 206) may not be provided to and/or identified by the one or more content servers 112, the one or more content servers 112 may be unaware of the web content's final destination location and/or identity. Further, the one or more content servers 112 may be unaware of any processing and/or requests (e.g., application programming interface (API) requests) to be performed to the web content.

For example, upon receipt of the web content from the one or more web servers 112, the one or more secure web containers 108 may process the web content to identify and/or extract text included in the web content. The one or more secure web containers 108 may then transmit the extracted text to a translation service 114 for translation. In some embodiments, the translation service 114 may be performed and/or operated by a third party device.

Because the one or more secure web containers 108 extracted and transmitted text from the web content to the translation service 114 (as opposed to simply transmitting the web content and/or a universal resource locator (URL) of the web content to the translation service 114), the translation service 114 may be unaware of the web content's origin location and/or identity. In this way, embodiments described herein provide a “double-blind” manner of providing an anonymous translation service of the web content (e.g., a web page that includes text) in the sense that both the provider of the web content (e.g., the one or more web servers 112) and the translator of the web content (e.g., the translation service 114) are unaware of each other, as well as any actions previously and/or to be performed to the web content.

After translation of the text is completed by the translation service 114, the one or more secure web containers 108 may receive translated text (e.g., a transformed version of the text extracted from the web content) from the translation service 114. The one or more secure web containers 108 may generate transformed web content (e.g., a web page that displays text in a language different than the language of the text extracted from the web content) using the translated text. In this manner, the user 102 may utilize various elements described herein to perform anonymous text translations of text included in web content (e.g., web pages) and to generate transformed web content based on the text translations.

The one or more secure web containers 108 may transmit the web content, extracted text, translated text, transformed web content, location and/or identity information associated with the user 102, the secure analysis application 104, the user device 106, the one or more secure web containers 108, the one or more egress nodes 110, the one or more web servers 112, and/or the translation service 114, user preferences, settings, and/or any other data to a cloud-based storage platform 116 for storage. The user 102 may access any data stored in the cloud-based storage platform 116 using the secure analysis application 104 and/or the one or more secure web containers 108.

FIG. 8 illustrates a system 800 for providing one or more users 802, 806 and/or user devices 804, 808 secure access to Internet content. One or more user devices 804, 808 may be connected to an enterprise network 810. An enterprise network may comprise one or more servers 812 and/or one or more network devices 814. In some embodiments, a user device 804, 808 may access Internet content from the Internet 840 through the enterprise network 810. However, such an arrangement may require the enterprise network 810 to monitor and/or filter incoming and/or outgoing data in order to secure the enterprise network 810 and/or user device 804, 808. Additionally or alternatively, a computing device 822 and/or associated database 824 may provide a remote cloud browsing session 820 (discussed below in more detail) to one or more user devices 804, 808. A remote cloud browsing session 820 may comprise a remote cloud browser, a computing process executed on a computing device 822 and/or associated database 824, computing hardware 822, 824 providing a remote cloud browser, and/or a remote cloud browser. For example, a user device 804, 808 and/or user 802, 806 thereof may request Internet content via a remote cloud browsing session 820, in response to which the remote cloud browsing session 820 may access the Internet content from an Internet content source 840, and subsequently provide second Internet content to the user device 804, 808 based on the Internet content requested by the user device (e.g. the second Internet content may be one or more image representations of the requested Internet content, and/or may be the Internet content scanned for and/or stripped of malicious data and/or content). Further, the remote cloud browsing session 820 and/or computing device 822 thereof may encrypt and/or log data associated with the user device and/or the requested Internet content (e.g. the request for the Internet content from the user device, the location associated with the user device, and/or the enterprise network associated with the user device). Additionally or alternatively, the remote cloud browsing session and/or enterprise network 810 may transmit Internet content (e.g. a file portion of the requested Internet content) to a second computing device 830 which may be located remotely from the remote cloud browsing session 820 and/or enterprise network 810. For example, the second computing device may serve as a third-party file inspector, and/or may scan and/or modify Internet content to detect and/or remove potentially malicious and/or objectionable content (e.g. before sending requested Internet content, the file portion thereof, and/or second Internet content based on the requested Internet content, to a user device 804, 808). In some embodiments, the second computing device 830 may be comprised in the enterprise network 810, may be comprised in the remote cloud browsing session, may be comprised in the user device 804, 808, may comprise a private network, may comprise a cloud computing device, may comprise a secure network, and/or may comprise file processing instructions.

System Description

As described above, the user 102 may initiate the secure analysis application 104 from the user device 106 (e.g., a local machine such as a laptop, a desktop, a computing device, a mobile device, and/or the like), which may communicate with a client interface to instantiate one or more secure web containers 108. The secure web containers 108, the client interface, and/or the secure analysis application 104 may be located on a single host machine (e.g., computing device) and/or may be distributed across a networked group of host machines.

Each secure web container 108 may have storage and/or processing capabilities as described herein to access web content, websites, web-based applications, and other resources hosted on web servers 112, respectively, on behalf of the user 102 of the user device 106. The secure web containers 108 may transcode data received from the web servers 112 to be securely presented to the user 102 at the user device 106 via the secure analysis application 104. This allows code from a web server 112 to be executed in a “sandbox” environment provided by a secure web container 108 instead of the user device 106, while still allowing the user to view and interact with content from the web server 112. Each secure web container 108 may be independently configurable and may be isolated from other secure web containers 108, including those residing upon a common host machine. By providing a highly isolated environment, each secure web container 108 minimizes the risks associated with accessing potentially dangerous web content for both the user device 106 and the secure analysis application infrastructure (e.g., including the plurality of secure web containers 108 and/or the secure analysis application 104). For example, each secure web container 108 may be isolated from the other secure web containers 108, in part, by having separate and transient session data that may be purged at the end of each session.

Furthermore, the user 102 of the user device 106 may simultaneously launch and operate multiple isolated sandbox environments (e.g., secure web containers 108) within the same user session (e.g., a period of time when the user is using the secure analysis application 104), each running a particular configuration of a remote browser provided by the secure web containers 108. Accordingly, the user 102 may access the same or different web servers 112 via egress nodes 110 with differently configured remote browsers simultaneously and independently. This allows the user 102 to have increased flexibility in crafting their digital identity when accessing web servers 112.

Browser Location

For jurisdictional or other reasons, it may be beneficial to control the physical location (e.g., IP address, physical processing device and/or storage device) of each secure web container 108 that acts as a remote browser to render or execute web content from a web resource (e.g., a web server 112). Multiple servers or other hardware for providing secure web containers 108 may be physically distributed across a region or even globally to provide this level of control.

Because multiple locations in the network (e.g., across an organization) may be available for utilization and/or routing by the secure analysis application 104, the secure web containers 108, and/or the egress nodes 110, a system administrator and/or the user 102 may select a particular browser location in the network for each of the secure analysis application 104 and/or the secure web container 108, as well as the one or more egress nodes 110, through which web content and/or information may be transmitted and/or routed. Additionally or alternatively, individual users 102 may, in some embodiments, select a specific network location for the secure analysis application 104, the secure web containers 108, and/or the egress nodes 110 when beginning a new session and/or instantiating a secure web container 108. An administrator may refer to at least one of a human user or a computer. In some embodiments, the administrator may be an intelligent computer that learns any of the input processes or information described herein over time, and refines any output processes or date over time.

The secure web container's location may not necessarily be available to the web servers 130 that are accessed. Instead, an egress node, as described below, may be used to prevent the web servers 130 from determining the location of the secure web container 120 (e.g., browser location) or the location of the user's user device 106.

Egress Node

As described above, the secure analysis application 104 and/or the secure web containers 108 may utilize a plurality of selectable egress nodes 110 through which the web content may be routed. An egress node 110 is a node by which an IP packet (e.g., having an HTTP GET method) enters into a public network (e.g., the Internet).

There are many scenarios where the user 102 may not want personally identifying information (e.g., their IP address and location, identity information, and/or the like) to be known by a web server 112 when requesting web content and may thus benefit from masking and/or modifying his/her digital persona. Furthermore, there may be advantages to selecting a particular egress node 110 location independently from the location of the user device 106 and/or the secure web containers 108. For example, web servers 112 may be able to alter the presentation of the web content or even the web content itself based on the perceived egress node 112 from which a request arrives. This may allow a malicious website, for example, to selectively expose the user 102 to malignant code based on their perceived egress node 112 and apparent location. When evaluating the potential threats of a website, the user 102 may thus benefit from being able to change their egress node 112, thereby changing their apparent location. It may be noted that this is but one of many scenarios where customisable attribution may be beneficial. Information security applications may be improved by this functionality, in that customizable attribution may benefit internal reliability or security testing of a company's own web resources.

As shown in FIG. 1A, the secure analysis application 104 may utilize various secure web containers 108 (e.g., remote web browsers) and/or various egress nodes 110, all of which may be provided by a networking infrastructure distributed across multiple regions or even globally (e.g., on separate devices). In some embodiments, a system administrator may allow the user 102 (e.g., an information security researcher) of the user device 106 to select a location for one or more of the secure web containers 108 and/or the egress nodes 110 when the user 102 begins a new session of the secure analysis application 104. The user's choice may be regionally limited by a specified range (e.g., within the continental United States). In some embodiments, the system administrator may provision a particular secure web container 108 and/or egress node 110 for utilization by the user 102 during a secure web browsing session. If neither the user 102 nor the system administrator specify a location for the secure web containers 108 and/or the egress nodes 110, a default secure web container 108 and/or egress node 110 may be automatically provided for routing web content from one or more web servers 112 during a secure web browsing session.

In some embodiments, an egress node 110 may be randomly selected for a session to avoid repeated access that might provoke suspicion from a targeted web server's administrator. The pool of egress nodes 210 from which a randomly selected egress node 210 may be chosen may share common traits such as region.

While the secure web containers 108, which may receive web content and execute web code from the web server 112 via one or more egress nodes 110, may prevent the web server 112 from determining the location of the user's user device 106, the selected egress node 110 may prevent the web server 112 from determining the location of even the secure web container 108. By allowing an egress node 110 to be located in the network separately and independently from the host machine hosting the secure web container 108 and/or the user device 106, the disclosed principles provide increased flexibility in establishing both remote browser locations (e.g., for jurisdictional reasons) and apparent locations (e.g., for probing the web server 112 with customizable attribution information).

In some embodiments, an organization having users of the secure analysis application may receive an expandable package (e.g., from the secure analysis application provider) that enables a system administrator or user of the organization to create and provide their own egress node 110 whenever and wherever they choose (e.g., on an user-provided machine and/or user device 106). This manually-generated egress node 110 may securely bind with the secure analysis application and may be disabled after one or more uses.

Browser Fingerprint

When the user accesses a website (e.g., web content) through a device (e.g., the user device 106), the web server 112 underlying the website may receive a browser fingerprint that defines various aspects of the device 106. For example, the browser fingerprint may describe the type of web browser, operating system, language support, plug-ins (including version designation), resolution, location, time zone, rendering capabilities of the user device 106, and/or an identity of the user 102. This information may be useful for a website (e.g., the web server 112) to provide a compatible presentation of web content.

However, utilizing a secure web container 108 and/or an egress node 110 during a browsing session may prevent the browser fingerprint of the user device 106 from being presented to the web server 112. Instead, locations and/or identities associated with the secure web container 108 and/or the egress node 110 may be provided to the web server 112 (even though the user 102 is accessing the web content via the secure analysis application 104 running on the user device 106) to thereby provide a complete, consistent, and/or credible anonymous identity for the user 102.

The secure analysis application 104 and/or the secure web containers 108 may comprise and/or communicate with a database (e.g., cloud-based storage platform 116) for storing default browser fingerprints that are organized by apparent location (e.g., as established by a secure web container 108 and/or an egress node 110). The database may be created by determining browser fingerprints that are most characteristic of a typical user device accessing the web content so that the user 102 is unlikely to stand out (e.g., is not suspicious) to the web server 112 during the browsing session.

The secure analysis application 104 may allow other elements of the browser fingerprint (e.g., an operating system, a type and/or location of web browser provided by the secure web containers 108, a type and/or location of an egress node 110, and/or the like) to be altered by a system administrator and/or the user 102. Certain high-level information (e.g., operating system information, browser information, software vendor information, user information, and/or the like) are generally contained within a user agent string that is placed in the header of outgoing messages. These elements are often more easily alterable. A system administrator and/or the user 102 may set policies within a policy database associated with the secure analysis application 104 (e.g., cloud-based storage platform 116), where the policies may allow the user 102 to change certain elements of the user agent information before or even after starting a session of the application. The policies may further dictate whether the user 102 is required to input authentication credentials when initiating a secure browsing session and/or accessing data associated with a secure browsing session. Additionally, the policies may dictate whether free form navigation is allowed or disallowed to the user 102 based on a user type, a level of authentication provided by the user, and/or the like. Additionally, settings associated with the secure browsing session such as a configuration of the secure analysis application 104, secure web containers, the cloud-based storage platform 116, and/or the like may be defined by one or more policies. The policies may be based on a variety of data including data collected, received, accessed, and/or determined by the secure analysis application 104 and/or the cloud-based storage system 116.

In some embodiments, the browser fingerprint may be randomly assigned for a session. This randomly assigned browser fingerprint may be selected from a pool of browser fingerprints which may each potentially correspond with the selected secure web containers 108 and/or selected egress nodes 110 associated with the session (e.g., as selected by the user 102, by the system administrator, or randomly).

Translation

As described above, the translation service 114 may be integrated with the secure analysis application 104 by communicating with the secure web containers 108. In many scenarios, a web server 112 may provide textual web content that is in a different language than desired by the user 102 at the user device 106. The secure analysis application 104 may help enable the translation of web content from the web server 112 without alerting and/or directly contacting the web server 130 with an external web translation request.

When the user 102 chooses to view a web page having foreign language text, the user 102 may send a request specifying the requested web content to the web server 112 via the secure analysis application 104 and/or the secure web container 108. For example, the request could be an HTTP GET message requesting content and may be routed from the secure web container 108 to the web server 112 by way of a particular egress node 110. The secure web container 108 may enable the user 102 to specify a preferred language for content to be translated into and received by the user 102. In some embodiments, the preferred language may be established during the initiation of the session associated with the secure web container 108.

The secure web container 108 may send a modified request to the web server 112, where identifying information (e.g., user agent information) of the user device 106 is removed and/or replaced with information associated with the secure web container 108 and/or the egress node 110 through which the request is routed and/or the web content is routed. This request may also be sent through a selectable or randomized egress node 110 (not shown), as described above.

The secure web container 108 may receive the requested content from the web server 112 through the egress node 110. The secure web container 108 may analyze the received content to identify textual content. If the secure analysis application 104 detects that the language of the identified textual content is different from a preferred language as specified by the user 102, the identified textual content and preferred language may be sent in a translation request to the translation service 114. It would also be possible for the secure analysis application 104 to send all textual content associated with a particular web page through the translation service 114 based on pre-configured information.

In some embodiments, the translation service 114 may provide an application programming interface (API) for sending and receiving information, and the translation request may be an API call. The secure web container 108 may receive translated textual content from the translation service 114. The secure web container 108 may then render a full presentation of requested content using the translated textual content (e.g., replacing the initially detected textual content with the translated textual content received from the translation service 114). In this manner, the user 102 may then view the requested content in the preferred language.

Alternatively, the user 102 of the user device 106 may first view the secure web container's 108 rendering of the web content in its native language (e.g., untranslated textual content). The user 102 may then request the secure web container 108 to provide translations for some or all of the textual content. The secure web container 108 may then communicate with the translation service 114 as described above to obtain the translated textual content and may then re-render a presentation for the viewing via the secure analysis application 104 running on the user device 106, having at least some of the textual content in the preferred language.

As the translation service 114 does not communicate directly with the web server 112, the web server 112 may be unaware that any translation is being performed. Instead, the web server 112 may merely detect a content request from the secure web container 108 (or a corresponding egress node 110) that resembles other requests typically received by the web server 112. Similarly, the translation service 114 may be unaware that the textual content was extracted from a particular web page.

Cloud-Based Storage

As described above, the secure analysis application 104 and/or the secure web container 108 may be integrated with a temporal or persistent cloud-based storage platform 116 capable of storing both transient and persistent data. In some scenarios, the user 102 may want to store web content and/or textual content downloaded from a web server 112 for analysis or other purposes. However, locally storing these files on the user device 106 may be non-ideal for various reasons including the sensitivity of the information contained in the files or the potential for the content to be malicious in nature.

To avoid resorting to storage on the user device 106 while still maintaining their transient and secure properties, secure web containers 108 may be securely integrated with the cloud-based storage platform 116 as described herein. For example, web content received by the secure web container 108 from the web server 112 may be sent to the storage platform 116 to be stored even after a session involving the secure web container 108 is completed.

The cloud-based storage platform 116 may then store the content, either permanently or temporarily, and may ensure that the content can only be accessed from authorized secure web containers 108 and not from other clients such as a local browser. Accordingly, the cloud-based storage platform 116 may be one mechanism by which data may securely persist after the secure web container 108 is collapsed and/or deactivated. The content may be accessed by the same user 102 or by a different user through a second secure web container 108 and a second user device (not pictured) at a later time.

The cloud-based storage platform 116 may be implemented with multiple layers to enhance security. In some embodiments, the cloud-based storage platform 116 may have encrypted data stores having nondescript naming conventions and flat or otherwise obfuscated directory structures. Additionally, the placement of new files within these data stores may be random or otherwise obscured. The files on the data stores may be encrypted through a variety of techniques. In some embodiments, the data stores may be encrypted using symmetric keys that are centrally managed by the provider of the secure analysis application 104. In other embodiments, the data stores may be asymmetrically encrypted using public keys provided by an end user, such that only the end user (and not even the secure analysis application provider) may privately access the files within the data store. As the contents of the data store may be encrypted, the files and directory stored by the data store may not be directly browsable (e.g., without a mapping table and/or an encryption key). Therefore, unauthorized systems such as a local browser, may be restricted from viewing the contents, and even the file directory or any other logical representation, associated with the data store. Accordingly, the data store itself may be conveniently stored in a third-party storage layer (e.g., Amazon's Simple Storage Service (S3)), within near or within a user's physical premises, or other storage locations. The cloud-based storage platform 116 may further comprise a mapping table linked to the encrypted data stores. In some embodiments, the mapping table may provide a meaningful data structure and set of file names for the data located in the encrypted data stores. The mapping table may, in some embodiments, be stored and provided by the secure analysis application provider.

In some embodiments, the above-described security features (e.g., encryption, random file placement, obfuscated directory structures) may all be implemented, and in other embodiments, a subset of the security features may be implemented in combination. Numerous other security features may additionally or alternatively be implemented.

The data stores of the cloud-based storage platform 116 may be divided into separate classes. For example, some data stores may be persistent whereas other data stores may be ephemeral or transient. This may provide greatly increase flexibility in establishing and enforcing data retention rules. For example, in some embodiments, a system administrator may want to restrict content that is associated with a particular secure web container, user, or web server from being stored for more than a certain amount of time. As such, content falling into this scope may be automatically placed within a transient data store of the cloud-based storage platform 116 where it may be deleted after a set amount of time or at a particular date and time. In some scenarios, a transient data store may expire at the end of a session or after a set number of web browsing sessions.

The cloud-based storage platform 116 may restrict access to the data that it contains. For example, the cloud-based storage platform 116 may be provisioned at an organization level, with portions dedicated to individual users and other portions acting as shared drives between multiple users or even an entire organization. A system administrator and/or the user 102 may select the geographic region or regions for the physical locations of the data store(s) used for their organization (e.g., for jurisdictional and/or user policy reasons).

The secure web containers 108 may provide users with file browsers for accessing the encrypted data store(s) within the cloud-based storage platform 116. The file browsers may also be used to upload files to a third-party service (not pictured) such as a file analysis service. The cloud-based storage platform 116 may further provide a secure external application programming interface (API) that allows individuals and organizations to pull data from or push data to the encrypted data stores without using the secure web containers 108.

The cloud-based storage platform 116 may be configurable by the user 102 or system administrators to accommodate many different scenarios. For example, a set of stored files may be restricted to a single user who may re-instantiate her/his secure web container 108-1 to access the content. The user 102 may also choose to share folders or particular files initially allocated to her/him with other users within an organization. When sharing data, the user 102 may specify a time period for which the data may be shared with another user, or the user 102 may share the data indefinitely. In addition, the user 102 may restrict certain file rights. These file rights may include downloading a shared file from the data store (e.g., to their secure web container 108), executing a shared file, editing a shared file, uploading to a shared folder, and printing a shared file, among other file rights. The user 102 or system administrators within an organization may also configure data retention rules, such that data is removed from the cloud-based storage platform 116 after an established period of time or a deletion-triggering event, as discussed above.

In some embodiments, the cloud-based storage platform 116 may be configured by policy to interact with the file system of the secure analysis application 104 and/or the user device 106. For example, a policy may require authentication credentials and/or authentication of the user 102 before utilizing and/or accessing data stored within the cloud-based storage platform 116, the secure system application 104, and/or the user device 106. If the system administrator enables this interaction, then the user 102 may have the ability to transfer content between her/his user device 106 and the cloud-based storage platform 116 (e.g., both upload and download). Conversely, a policy may restrict interaction between the user device 106 and the cloud-based storage platform 116, so that users may be able to download content to the cloud-based storage platform 116 when visiting web servers 112 via the secure analysis application 104 and/or the secure web container 108 but may not be permitted to transfer files between the file system of the user device 106 and/or the secure web container 108 and the cloud-based storage platform 116 in either direction.

Encrypted Logging

Session data that is accumulated during the use of a secure web container 108 may generally be purged from the secure web container after the session is complete. However, in some embodiments, log entries corresponding to the sessions may be stored and compiled in a log database (e.g., cloud-based storage platform 116) before or upon session completion. For example, the log database may store log entries corresponding to each session for internal analysis or record keeping (e.g., within an organization associated with the secure analysis application 104).

In some embodiments, the log databases may retain log entries for a set time period and/or on a rolling basis (e.g., 90 days) before log entries are automatically deleted. The log entries may include various types of data including user data and session data (e.g., host machine identifiers, access times, and/or session durations). The log entries may also have a parameter indicating the organization to which they belong. This organization-level separation allows a system administrator (e.g., the user 102) within an organization to establish the particular types of data that are logged as well as the period for which different types of logged data are stored for their organization.

Furthermore, the system administrator may provide a public key to the log database for encrypting their organization's logs. The system administrator may subsequently request and receive their encrypted logs through an external application programming interface (API) of the now-encrypted log database. The encrypted logs may then be decrypted within the system administrator's local network or on their local machine through a private key that matches the public key provided to the log database for encryption. Other encryption systems may be implemented to ensure that access to the encrypted logs is restricted to those having the correct credentials (e.g., system administrators within an organization to which the logs relate).

In some embodiments, the system administrator may increase the granularity of the data captured and stored within their encrypted log database. For example, logging functionality may be increased to include user navigation data (e.g., the web resources accessed, with time stamps), administrative changes to the secure analysis application's configuration, authentication events, session events, and web form post data (e.g., data provided to web resources).

URL Forwarding

With further reference to FIG. 1A, the user 102 may wish to access web content associated with a particular URL (e.g., a hyperlink, a web address, a web page, and/or the like). For example, the user 102 may input a URL and/or web address into a browser window (e.g., a local or unsecure browser window on the user device 106). However, in some instances, web content associated with a desired URL may unknowingly be malicious, may include harmful artifacts, and/or may otherwise present security risks to the user device 106 if accessed using an unsecure browser. Embodiments described herein with reference to URL forwarding techniques may enable the user 102 to access web content associated with a desired URL in a secure manner using one or more secure web containers 108 regardless of which client web browser the user 102 used to input the desired URL.

For example, the user 102 may utilize a typical unsecure web browser local to the user device 106 to surf the web or otherwise access web content associated with various URLs (e.g., web content comprised in various web servers 112). When the user 102 inputs and/or selects a URL (e.g., through a web address, a web page, or other web content) in a browser window of the web browser local to the user device 106, a web gateway including one or more gateway policies, the secure analysis application 104, the user device 106, or another device (e.g., an enterprise device such as a network server, or a firewall local to or in communication with an enterprise network on which the user device 106 operates, a plug-in of the web browser running on the user device 106, a client interface, or a client agent running on the user device 106 and associated with the secure analysis application 104) may determine, based on the URL, that web content associated with the URL may not be secure (e.g., may present security risks to the user device 106 and/or another device).

Importantly, it may be unknown whether web content associated with an inputted or selected URL is malicious. As such, a network administrator may not wish for the web content to be accessed or executed locally (e.g., local to the user device 106 or network). The network administrator may thus forward the URL associated with web content of an unknown profile and/or potentially malicious characteristics to the secure analysis application 104 for remote execution of the web content. In this manner, the user 102 may be provided with “siloed” access to the web content associated with the URL without exposing the user device 106 or network to unknown and/or potentially harmful web content.

In some embodiments, the determination of whether web content associated with a desired URL is unknown or potentially harmful to the user device 106 or network may be made by a human network administrator. For example, the network administrator may review a list of web content requests. If the network administrator is unfamiliar with the source of the web content and thus does not want to risk exposing the user device 106 and/or network to potential security risks, the network administrator may forward the associated URL to the secure analysis application for creation of a secure web browsing session. The network administrator may determine whether the web content should be executed locally based on an unknown status, a potentially harmful status, and/or a web content category (e.g., social media, pornography, hate speech, and/or the like).

In other embodiments, the determination of whether web content associated with a desired URL is unknown or potentially harmful to the user device 106 or network may be automated. For example, the user device 106 may receive a URL or identify a URL comprised in user input received at the user device 106 (e.g., a click or other selection of a hyperlink, a selection of an image, a video or audio content). The secure analysis application 104, which may include various gateway policies for routing web traffic or providing access to web content, is operable to identify whether web content selected by or directed to the user 102 is potentially unsafe. If a match between the received/identified URL and a URL in the database of URLs known or suspected to be associated with harmful web content is determined, the received/identified URL may be determined to be associated with potentially harmful web content. If no match between the received/identified URL and a URL in the database of URLs known or suspected to be associated with harmful web content is determined, the user device 106 may proceed with accessing and/or retrieving web content associated with the received/identified URL, potentially even with the unsecure web browser.

Alternatively, if a match between the received/identified URL and a URL in the database of URLs known to be associated with safe web content is determined, the user device 106 may be enabled to proceed with accessing and/or retrieving web content associated with the received/identified URL using the unsecure browser and/or any other approved web browsing mechanism. If no match between the received/identified URL and a URL in the database of URLs known to be associated with safe web content is determined, the received/identified URL may be determined to be associated with potentially harmful and/or otherwise unknown web content. In some embodiments, a URL determined to be associated with potentially harmful and/or otherwise unknown web content may be stored in a database of URLs known to be associated with harmful web content.

In addition to blacklists of URLs known or supposed to be associated with potentially harmful web content and whitelists of URLs known or supposed to be associated with safe content, the secure analysis application 104 may also use adaptive means of determining danger levels associated with URLs. For example, the secure analysis application 104 may perform visual and/or auditory analysis of web content prior to providing the user device 106 with access to the web content to determine whether the web content includes any objectionable content.

Additionally, the secure analysis application 104 or web gateway may further determine a risk level associated with the received/identified URL. Determination of the risk level may include analysis of a variety of factors such as web content, URL type, attributes of a destination web page associated with the URL, a time of a request for the web content associated with the URL, a location of the user device 106, and a location of the web server 112 from which the web content is to be requested. Once determined, the risk level may be compared to a threshold value associated with an acceptable risk level. If the determined risk level meets or exceeds the threshold value, the received/identified URL may be determined to be associated with potentially harmful and/or otherwise unknown web content.

Once the received/identified URL is determined to be associated with potentially harmful or otherwise unknown web content, the secure analysis application 104 (e.g., web gateway) may establish an encrypted communication connection between the user device 106 and one or more secure web containers 108. In some embodiments, parameters of the established encrypted communication connection may be based at least in part on the received/identified URL and/or web content associated with the received/identified URL.

For example, the secure analysis application 104 or web gateway may identify, select, and/or initialize the one or more secure web containers 108 for creating a secure environment in which the user 102 may access the potentially harmful and/or otherwise unknown web content associated with the received/identified URL. For example, a particular amount of memory and/or processing power of each of the one or more secure web containers 108 may be partitioned for accessing the potentially harmful and/or otherwise unknown web content associated with the received/identified URL. Techniques and systems for providing secure web containers 108 as described herein are described in greater detail in U.S. patent application Ser. No. 13/076,421, filed Mar. 30, 2011 and entitled “Disposable Browsers and Authentication Techniques for a Secure Online Environment,” and U.S. patent application Ser. No. 13/844,026, filed Mar. 15, 2013 and entitled “Secure Web Containers for a Secure Online Environment,” both of which are incorporated by reference in their entireties. Additionally, the secure analysis application 104 may select locations (e.g., IP addresses, devices on which to operate, and/or the like) of the one or more secure web containers 108 and/or egress nodes 110 to be used when accessing the potentially harmful and/or otherwise unknown web content associated with the received/identified URL from one or more web servers 112.

The received/identified URL is then transmitted from the user device 106 (e.g., forwarded) to the one or more secure web containers 108 via the encrypted communication connection. Once received by the one or more secure web containers 108, the received/identified URL may be used by the secure analysis application 104 and/or the one or more secure web containers 108 to identify one or more web servers 112 associated with the desired web content associated with the received/identified URL. The secure analysis application 104 and/or the one or more secure web containers 108 may also use the received identified URL to initialize and/or select one or more egress nodes 110 to be used during retrieval and/or access of the web content.

The one or more secure web containers 108 may then retrieve the web content associated with the received/identified URL from the one or more identified web servers 112 through any selected and/or initialized egress nodes 110. In some embodiments, the one or more secure web containers 108 may store the retrieved web content. In other embodiments, the one or more secure web containers 108 may not store the retrieved web content.

Once retrieved and/or otherwise accessed by the one or more secure web containers 108, the desired web content associated with the retrieved/identified URL is then rendered at the one or more secure web containers 108. By rendering the web content at the one or more secure web containers 108 (e.g., in a secure environment and at an “arm's length” from the user device 106), the user device 106 is protected from unwanted exposure of potentially harmful web content. Further, by utilizing the one or more secure web containers 108 and the selected egress nodes 110 to retrieve and/or access the web content from the web servers 112, the user device 106 (and thus the identity of the user 102) may be hidden from the web servers 112. Similarly, the identity of the web servers 112 may be hidden from the user device 106 and/or the user 102 during retrieval and/or accessing of the web content.

The user 102, using the user device 106, may remotely access the web content being rendered on the one or more secure web containers 108 by way of a client agent and/or interface running on the user device 106 and associated with the secure analysis application 104 and/or other system elements as described herein. For example, the client interface running on the user device 106 may enable the user 102 to view the web content rendered on the secure web container(s) 108 via the encrypted communication connection established between the user device 106 and the one or more secure web containers 108. Again, techniques and systems for rendering web content at secure web containers 108 as described herein are described in greater detail in U.S. patent application Ser. No. 13/076,421, filed Mar. 30, 2011 and entitled “Disposable Browsers and Authentication Techniques for a Secure Online Environment,” and U.S. patent application Ser. No. 13/844,026, filed Mar. 15, 2013 and entitled “Secure Web Containers for a Secure Online Environment,” both of which are incorporated by reference in their entireties. The user 102 may also utilize a web browser local to the user device 106 to access the web content via the secure web containers 108 as described herein.

In some embodiments, the secure analysis application 104 may generate and/or otherwise present to the user 102 on the user device 106 a new secure web browser window (e.g., the user interface 300 of FIG. 3, a client agent and/or interface running on the user device 106 and associated with the secure analysis application 104, and/or the like) through which the user 102 may access and/or view the content rendered on the one or more secure web containers 108. In this manner, regardless of which web browser the user 102 used initially to request web content, the user 102 is provided with secure access to the requested web content at an “arm's length” through a secure web browsing session as described herein. In some embodiments, the user 102 may request the potentially harmful web content in a first browser window (e.g., an unsecure browser), and then be enabled to view the requested web content in a second browser window (e.g., a secure browser and/or a client agent and/or interface running on the user device 106 and associated with the secure analysis application 104). The web content may also be accessible to the user 102 via the same web browser local to the user device 106 that the user 102 utilized to input the URL.

In some embodiments, the user 102 may be provided with a notification that requested web content and/or web content associated with a provided URL is potentially harmful to the user device 106. For example, the secure analysis application 104 may generate, upon determining that requested web content may be potentially harmful to the user device 106, the notification and present the notification to the user 102 on the user device 106 via a client agent and/or interface running on the user device 106 and associated with the secure analysis application 104. The notification may be presented to the user 102 at various times during the described URL forwarding processes. In some embodiments, the notification may include a generated risk level score and/or other identifying information associated with the determination that requested web content may be potentially harmful to the user device 106.

Once the user 102 has accessed and/or viewed the requested web content, the secure analysis application 104 may terminate the encrypted communication connection between the user device 106 and the one or more secure web containers 108, the communication connection between the one or more secure web containers 108, the egress nodes 110, and/or the web servers 112, and/or the like. In embodiments described, when accessing web content through secure web containers 108, no web code is transmitted to the user device 106, and instead the web content may be transmitted to and/or rendered on the one or more secure web containers 108. The user device 106 may simply be provided access to the one or more secure web containers 108 (e.g., images and/or audio of the web content may be presented on the user device 106, but the actual web code or content remains at the one or more secure web containers 108), which may enable the user 102 to view the requested web content at an “arm's length.”

In some embodiments, authentication of the user 102 may not be required by the secure analysis application 104 to create a secure web browsing session or for the user 102 to access the web content. For example, a user-specific digital authentication certificate associated with the user 102 (e.g., a password, a login credential, or a key) may be stored in the cloud-based storage system 116 for quick recall by the secure analysis application 104 during the web browsing session. In some embodiments, the authentication certificate may be stored in a profile storage unit 232 and accessed by a profile management unit 210 as described below with reference to FIGS. 2A and 2B. Alternatively, the authentication certificate may be stored on a common access card (CAC) or in another location not local to the secure web containers 108. In some embodiments, the secure analysis application 104 may be configured to automatically retrieve the authentication certificate from the user device 106 or another location, such as from a CAC via an encrypted communication connection. The secure analysis application 104 may retrieve the authentication certificate when initializing the secure web browsing session or various times (e.g., intervals or as needed) during the secure web browsing session.

The secure analysis application 104 may then be configured to automatically provide the authentication certificate to the web servers 112 or other devices as required during the web browsing session. In this manner, the user 102 may be enabled to access web content during the secure web browsing session without having to continually input user authentication credentials.

FIG. 1B illustrates an exemplary system 101 performing URL forwarding operations as described herein. Similar in structure to system 100 of FIG. 1A, system 101 of FIG. 1B provides a user 102 of a user device 106 with secure access to potentially harmful web content rendered on a secure web container 108.

For example, at (1), the user 102 may input a web address (e.g., a URL) in an unsecure web browser local the user device 106 (e.g., may type a web address in an address bar of a browser window, may select an image, audio, text, and/or a video, may select a hyperlink, may open an email attachment and/or other file, and/or the like). The user 102 may also input the web address using a client agent and/or interface (e.g., a secure browser) running on the user device 106 that is associated with the secure analysis application 104.

At (2), a browser plug-in running on the user device 106 (e.g., the client agent or interface associated with the secure analysis application 104 and/or a web gateway that includes various gateway policies) may determine, using techniques described herein, that web content associated with the web address is potentially harmful to the user device 106 and/or another device on a shared network. In some embodiments (not shown), the web address may be forwarded from the user device 106 to a secure analysis application 104 running on the cloud, and the secure analysis application 104 and/or web gateway policies may perform the determination of whether the web content associated with the web address is potentially harmful.

At (3), and after the web content is determined to be potentially harmful, the secure analysis application 104 may initialize a secure web container 108 for hosting a secure web browsing session during which the web content may be accessed. The secure analysis application 104 may also initialize an egress node 110 through which the secure web container 108 may retrieve the web content from the web server 112. The secure analysis application 104 may further establish a secure encrypted communication connection between the user device 106 and the secure web container 108. The secure analysis application 104 may also establish a communication connection between the secure web container 108 and the web server 112 comprising the web content associated with the web address, wherein the communication connection between the secure web container 108 and the web server 112 includes the egress node 110.

At (4), the web address is forwarded from the user device 106 to the secure web container 108 via the encrypted communication connection. In some embodiments, the secure analysis application 104 may be used to forward the web address to the secure web container 108 based on one or more web gateway policies.

At (5), the secure web container 108 uses the web address to retrieve the web content associated with the web address. The web content may be retrieved by the secure web container 108 and from the web server 112 via the established communication connection between the secure web container and the web server 112. In some embodiments, the web content passes through the egress node 110 during retrieval. In some embodiments, the secure analysis application 104 may itself retrieve the web content.

At (6), the secure web container 108 renders the web content. Importantly, rendering the web content at the secure web container 108 ensures that the web content is not transmitted to the user device 106, thereby protecting the user device 106 from potential harm. In some embodiments, the secure analysis application 104 may render the web content at the secure web container 108.

At (7), the user 102 may use the user device 106 to access the web content rendered at the secure web container 108 via the encrypted communication connection. For example, the user 102 may utilize the client agent and/or interface (e.g., a secure browser) running on the user device 106 that is associated with the secure analysis application 104 to access the web content. The user 102 may also utilize the unsecure web browser local to the user device 106 to access the web content in a new window populated with a hyperlink associated with the web content rendered on the secure web container 108. In this manner, the web content is not transmitted to the user device 106. In some embodiments, a notification may be presented to the user 102 indicating that a new secure browsing session has been initiated to enable the user 102 to view potentially harmful web content.

A detailed process flow of the URL forwarding process is found below in FIG. 6 and its accompanying text.

Networked computing environment such as those provided by a communications server may include, but are not limited to, computing grid systems, distributed computing environments, cloud computing environment, etc. Such networked computing environments include hardware and software infrastructures configured to form a virtual organization comprised of multiple resources which may be in geographically disperse locations.

In some embodiments, the network described herein may include any wireless and/or wired communications network that facilitates communication (e.g., transmission and/or receipt of between the computing environment 200 and any other device. For example, the one or more networks may include an Ethernet network, a cellular network, a computer network, the Internet, a wireless fidelity (Wi-Fi) network, a light fidelity (Li-Fi) network, a Bluetooth network, a radio frequency identification (RFID) network, a near-field communication (NFC) network, a laser-based network, and/or the like.

User Interface

Referring now to FIG. 3, FIG. 3 shows an exemplary graphical interface 300 for a secure analysis application that may be presented on a user device 302 of a user 304. A user may instantiate multiple secure web containers in one common session of the secure analysis application. Each secure web container may correspond with a window displayed within a client agent and/or interface running on the user device 302 and associated with the secure analysis application.

As discussed above, the different secure web containers may have distinct configuration settings. As shown in FIG. 3, these configuration settings may be displayed within each window in a message bar 306 to allow the user 304 to track each browsing session more carefully. In some embodiments, the message bar 306 may include information associated with the session such as user agent information 308 (and/or other aspects of the browser fingerprint), a browser location 310 (e.g., the IP address and/or the regional location of the selected secure web container), and an egress node 312 location (e.g., the IP address and/or the regional location of the selected egress node). The user may adjust some or all of these settings by interacting with the message bar 306. Some settings, such as those pertaining to the egress node 312 may be adjusted before initiating a session, and some settings, such as the operating system, type of web browser and/or other user agent information 308 may be may be adjusted either before or during the session. In some embodiments, some or all of these settings may be pre-defined and fixed by a system administrator. In general, as a user may have multiple secure analysis application sessions and/or multiple secure web containers open simultaneously, the message bar 306 may help the user remember and preserve the separation of each session. Once a connection has been established between the user device 302 and a web server (e.g., a provider of content), web content 314 may be displayed on the user device 302.

In some embodiments, a cloud browser may operate as a standalone browser and/or within a dedicated cloud browsing environment. In some embodiments, a cloud browser may transparently push and/or publish data to a user device, and may be implicitly triggered based on actions performed on a user device and/or by a third-party employing a cloud browser to deliver and/or inoculate content delivered to a user device.

Selective Content Representation

During a typical web browsing session using a web browser other than the cloud browser described herein, content may be displayed to users in an inefficient manner. For example, when a user clicks on a hyperlink to open a web page, a generic browser may automatically retrieve and display all of the information on that web page (e.g., data, metadata, images, text, videos, audio, and/or the like), regardless of whether the user desires to view or use that information. As such, a generic browser may waste computing or network resources such as bandwidth, processing power, and/or the like by retrieving and displaying information that may never be viewed and/or required by a user.

Advantageously, the cloud browser described herein (e.g., the secure analysis application 104 and/or the secure web container 108 of FIGS. 1A and 1B) may selectively retrieve web content from a web server (e.g., web server 112 of FIGS. 1A and 1B) and/or selectively display the web content to a user (e.g., user 102 of FIGS. 1A and 1B). In some embodiments, the cloud browser may track a display window of a user device (e.g., user device 106 of FIGS. 1A and 1B) to determine which portion(s) of a web page are actually visible to the user of the user device. The cloud browser may then retrieve and/or display only information that is within a visible portion of the web page. The cloud browser may not retrieve and/or display information that is determined to be outside of the visible portion of the web page. By retrieving and/or displaying only the information that is visible to the user, the cloud browser may utilize computing resources in a more efficient manner (e.g., conserve bandwidth, processing power, and/or the like). In some embodiments, raw HTML content and/or original form of web data may be transcoded into a display version and/or according to a display protocol. Bandwidth savings of a selective content representation embodiment may be realized due to reduced display data relative to raw and/or original web content that would otherwise be executed. A selective content representation embodiment may employ just-in-time just-in-time rendering, processing, display, and/or download of content accessed and/or retrieved during a cloud browser session. In some embodiments, a cloud browser may transmit an image, video, audio data, modified web content (e.g. HTML code), and/or a subset of web content (e.g. CSS files and/or Javascript code).

In some embodiments, selective retrieval and/or display of web content may occur in response to user actions. As the user interacts with the web page and/or the web page content, the visible portion of the web page may change. For example, as the user scrolls down on a web page, new web content may become visible to the user. The cloud browser may continuously monitor the visible portion of the web page being displayed to the user throughout a browsing session. Based on continuously determining which portion(s) of the web page are visible to a user, the cloud browser may determine which content is within a viewable portion of a web page, and then retrieve content within the viewable portion.

Upon a user of a user device requesting to visit a web page or access other kinds of stored web content, the web browser may first determine a portion of the web page that is visible to the user. In some embodiments, determining a portion of the web page that is visible to the user may include detecting one or more displays of the user device. For each display, the cloud browser may receive from the display and/or otherwise identify display characteristics such as screen size, a resolution, a number of pixels, a device identification number, a scrolling speed, a touch or tapping speed, a gesture speed, a brightness, a contrast, user interface overlays, and/or the like. These display detection steps may occur before web content is retrieved from a web server, before web content is displayed on the user device, and/or substantially simultaneously to receiving a request for web content. The display characteristics of each user device display may be stored in a database associated with the cloud browser and may be configurable by an administrator on a per-session and/or per-user basis.

Based on the display characteristics, the cloud browser may determine a viewable window within which web content may be displayed on the user device. For example, the cloud browser may determine that the screen resolution of a user device is a first resolution. The cloud browser may also determine that a user interface overlay (e.g., a button, a menu, and/or the like) having a second resolution and/or at a particular location on the user device display hides a portion of the first resolution so that web content is partially hidden as it is presented to the user. As such, the cloud browser may determine that the viewable portion of the user device display is a third resolution equal to the first resolution minus the second resolution. The cloud browser may continuously monitor how the viewable range of the user device display changes in response to user actions, such as menu opening and closing, button clicking, gestures, scrolling, and/or the like.

The user device may include a plurality of user devices and/or displays, such as external monitors. The cloud browser may therefore compile all of the display characteristics for each individual user device and/or display. Each display may be independently configurable and have differently-sized and/or differently-shaped viewable portions and/or windows for displaying web content. The cloud browser may also detect when a display characteristic of the user device changes (e.g., if the user switches from a mobile device display to a desktop display, if the user adds an external display to his user device, if the user scrolls, zooms, performs a gesture such as a click, a swipe, or a swim, or select an interface portion (e.g., a menu button)) and update the viewable window accordingly.

Once the viewable window of the user device is identified, the cloud browser may then retrieve web content of a web page that is within the viewable window of the user device. Again, the cloud browser may only retrieve the web content that is visible to the user at a present time. The cloud browser may thus not retrieve web content that would not be visible to the user on the user device display. Once retrieved, the cloud browser may present and/or display the retrieved web content in the viewable window of the user device display. In some embodiments, a cloud browser may operate in an “open” environment, such that an IP address and/or web resource may be accessed. In some embodiments, a cloud browser may operate in a “closed” environment such that only a pre-determined set of IP addresses, web resources, and/or web applications may be accessed.

In some embodiments, the cloud browser may identify a portion of the desired web content that is within the viewable window of the user device display. Identifying the portion of the desired web content that is within the viewable window of the user device display may occur either prior to or after retrieving the web content. For example, in some embodiments, the cloud browser may simply request, from the web server, web content that is located and/or visible within the viewable window of the user device identified by the cloud browser. In other embodiments, the cloud browser may retrieve all of the web content associated with a web page, and render it at a secure location (e.g., in a secure web container 108 of FIGS. 1A and 1B). Once the web page is rendered at a location away from the user device, the cloud browser (e.g., the secure analysis application 104 of FIGS. 1A and 1B) may then identify which web content and/or portion(s) of the web content is located within the viewable window of the user device display. Once the web content that will be visible to the user on the user device display is identified, the cloud browser may selectively display only that web content on the user device.

Identifying the web content that is located within the viewable window of the user device display may include comparing pixel locations of the user device display that are visible to the user and pixel locations of web content on the web page. Comparing pixel locations may include analyzing an HTML file, a CSS file, and/or other coding script to identify the web content locations (e.g., locations of objects and/or other web content in a web page layout).

The cloud browser may further be enabled to identify a type of web content comprised in a web page. For example, the cloud browser may identify and tag, store, and/or modify content based on whether it is a video, audio, an image, text, a button, and/or the like. Based on an identified content type, the cloud browser may selectively retrieve and/or display the web content. For example, the cloud browser may initially retrieve all text and/or functional objects (e.g., menu buttons) on a web page, but only retrieve content larger than a particular file size and/or requiring more than a particular bandwidth (e.g., videos, audio, images, and/or the like) as they come into the viewable window of the user device. In this manner, the cloud browser may conserve computing resources.

As described in more detail herein, displaying web content on the user device may include transmitting web content to the user device for display. Displaying web content on the user device may also include rendering web content at a location remote to the user device, and then providing an encrypted image-based representation to the user device over a secure communication connection. In some embodiments, displaying web content on the user device may further include transcoding web content from a first format to a second format. For example, transcoding web content may include compressing a file object and/or other web content into a compressed image format and/or another format (e.g., video format, audio format, and/or the like). Web content of the second format may be more heavily compressed than web content of the first format, may have a different file extension than web content of the first format, may require less bandwidth than the web content of the first format, and/or the like.

User actions may dictate which web content is displayed to the user. For example, as the user scrolls down a web page, web content located further down on the web page will need to be displayed to the user. Based on user actions, the cloud browser may retrieve and/or display the web content being requested by the user. User actions may include scrolling, clicking, swiping, swimming, zooming, moving a pointer and/or mouse, selecting a button or other user interface portion, performing a gesture, providing a biometric input (e.g., eye scan, fingerprint, breath sample, hair sample, blood sample, and/or the like), and/or any other user input.

In response to user actions during operation, web content that was previously viewable (e.g., determined to be located within the viewable window of the user device display) may move outside of the viewable window of the user device display. In some embodiments, the cloud browser may store this no-longer-viewable web content in a temporary cache or other storage location for quick recall in case the user desires to view it again. The no-longer-viewable web content may be stored for a predetermined period of time, after which the web content may be deleted. Alternatively, the cloud browser may simply delete this web content. In this instance, if the user wishes to view the no-longer-viewable web content again, the cloud browser may retrieve and/or display it again.

Extended Policy Control

The cloud browser described herein may include a variety of policy controls for giving administrators an ability to limit, monitor, and/or otherwise govern utilization of computing resources. As elaborated upon above, the cloud browser may include an administrative portal that enables a user to set various parameters for one or more browsing sessions. The administrative portal may also enable an administrator and/or end user to set parameters for other users, individually and/or across an entire agency or organization. In some embodiments, a cloud browser and/or administrative portal thereof may provide centralized visibility into cloud browser activity and/or usage, and/or may provide centralized control of cloud browser and/or associated computing device resource access and/or usage. In some embodiments a cloud browser environment (which, e.g., may comprise an administrative portal) may provide full audit, logging, visibility, and/or traceability of cloud browser activity. In some embodiments, a cloud browser environment may provide misattribution (e.g. modify information associated with a web browsing session, such as point of geographic location and/or IP address, from computing resources providing web content) and/or non-attribution (e.g. hide and/or obscure information associated with a web browsing session from computing resources providing web content) features for enablement by an administrator and/or end user, e.g., via one or more egress nodes.

For example, the administrative portal may enable an administrator to select, set, and/or modify one or more network locations for user devices, secure web containers, egress nodes, content servers, web servers, and/or the like. IP addresses of one or more devices described herein may be assigned to a user based on a user status (e.g., a level of seniority, a security clearance level, an agency or organizational designation, an employee title, a project scope, and/or the like). For example, all employees of a particular organization may be assigned one or more IP addresses for masking purposes, device utilization, storage locations, network access points, and/or the like. Individual employees may also be assigned unique IP addresses for one or more of the same purposes listed above. Multiple IP addresses and/or one or more devices may be assigned to a user for different reasons. The policy settings described herein may be applied to a user on a per-user basis, a per-project basis, a per-session basis, an organizational basis, and/or the like. An administrative portal may be alternatively or additionally referred to as a policy portal and/or console. A policy portal may be used in combination with a cloud browser. A policy portal may allow and/or facilitate the setting of user privileges and/or data tracking requirements.

In some embodiments, a user may define where and/or what data (e.g. user-identifying information) is to be stored, including an option such that no data is stored and/or stored data is deleted at the end of a browser (e.g. cloud browser) session (i.e. “right to forget” option). In some embodiments, a user may request information regarding where data (e.g. user-identifying information) is stored. In some embodiments, a user may request information regarding what data (e.g. user-identifying information) is stored, e.g. based on data accessed and/or downloaded during a cloud browser session. In some embodiments, a user may request to access, view, and/or receive stored data. In some embodiments, a user may request deletion, removal, relocation, and/or “purging” of stored data (e.g. user-identifying data generated and/or stored during a cloud browsing session). In some embodiments, a cloud browser and/or cloud browser application may comply with and/or execute one or more of the above user definitions and/or requests. In some embodiments, a cloud browser and/or cloud browser application may ensure data (e.g. user-identifying data generated during a cloud browsing session) is stored in a GDPR-compliant region (e.g. regardless of the location of a user, user device, and/or remote computing device executing a cloud browser session).

In addition to IP address assignment, the cloud browser may further enable monitoring and control of computing resource usage. In some embodiments, the administrative portal may enable an administrator to set limits and/or thresholds on utilization of various computing resources. For example, the administrator may allocate a particular bandwidth cap and/or quota to a user staffed on a particular project. Additionally and/or alternatively, a maximum utilization of processing power, a maximum number of egress nodes, a maximum cellular and/or wireless network data usage, a maximum satellite utilization time, a maximum storage amount, a maximum number of utilized devices, a maximum number of displays, a maximum number of downloads, a maximum number of web content requests, a maximum utilization of other computing resources, and/or the like may be assigned to a user. In general, an administrator, organization, and/or user may set a usage threshold with respect to one or more parameters, including bandwidth, time of day, content type, content category, URL, domain, session duration, etc. In some embodiments, a user device, cloud browser application, and/or server may enforce a usage threshold. In some embodiments, a user may request an exemption from a usage threshold and/or quote. Additionally or alternatively, an administrator and/or organization may receive a notification of the user request, and may further approve and/or reject the user request for permission and/or exemption. Again, the policy settings described herein may be applied to a user on a per-user basis, a per-project basis, a per-session basis, an organizational basis, and/or the like. The policy settings described herein may also be applied temporally (e.g., for a particular duration of time, at a particular time of day, during a particular web browsing session, and/or the like). A user may also be limited by a number of applications that can be accessed, a number of web sites that can be accessed, a number of requests for web content, and/or the like.

In some embodiments, policy controls may be applied on an organizational basis. For example, a governmental agency comprising a team of multiple users may be allocated a maximum bandwidth. Each team member may be assigned a particular bandwidth cap individually. Alternatively, individual team members may not be assigned a particular bandwidth cap, but instead their usage may be limited by how the team as a whole is utilizing resources. Resource usage may be metered on a per-user and/or aggregate (e.g. per-organization) basis, and may be used to enforce usage limits and/or usage prioritization of particular users and/or organizations. In some embodiments, a cloud browser application may manage user and/or organizational credentials.

In accordance with embodiments described herein, the cloud browser may include multiple cloud browsers. Each cloud browser may communicate with one or more central administrative servers and/or portals. In this manner, multiple cloud browsers may be monitored and/or configured from one location and/or by one user.

The cloud browser may track usage of computing resources during a web browsing session. The cloud browser may continuously sample and/or determine various characteristics of computing resource utilization, such as bandwidth usage, time and/or day of session, processing power utilization, data usage, storage space utilization, and/or the like. If a user approaches and/or exceeds a predetermined limit (e.g., a bandwidth limit), the cloud browser may transmit a notification to an administrator and/or the user notifying that utilization of a computing resource is at risk of being overused, per policy controls.

Because a plurality of users may utilize separate cloud browsers to accomplish a common project, each cloud browser may transmit computer resource utilization reports to a central control portal (e.g., administrative portal). These reports may be sent at periodic intervals and/or continuously. In this manner, an administrator may be enabled to monitor usage of computing resources, and then allocate them more efficiently. Reports may include logs of browsing sessions as described above, logs of computing resource usage, device identification numbers, user identification, IP addresses, and/or the like.

Similar to the resource allocation unit 224 of FIGS. 2A and 2B, the administrative portal may be enabled to allocate computing resources between one or more users to ensure efficient utilization of computing resources. For example, within a common organization, first and second users may be initially allocated the same amount of network bandwidth. During simultaneous browsing sessions, the first user may approach and/or reach his cap of allocated bandwidth (e.g., exceed a first bandwidth threshold). If the second user is not utilizing her allocated bandwidth beyond a second bandwidth threshold, then the cloud browsers may allocate an amount of the second user's network bandwidth to the first user. The same principle may apply across an entire organization or users so that computing resources are utilized efficiently. Thresholds for computing resource utilization(s) may be configurable by one or more users.

An administrator may set an optimal efficiency rate above which individual cloud browsers, or a system including a plurality of cloud browsers, must operate. Depending on a number of active browsing sessions, available computing resources, demand for computing resources, and/or the like, computing resources may be allocated between cloud browsers to ensure desired efficiency is maintained.

If a user exceeds a threshold of bandwidth usage, the cloud browser may throttle the utilization of computing resources to maintain operation of the cloud browser and associated features during a browsing session. Alternatively, if a user exceeds a threshold of bandwidth usage, the cloud browser may terminate a browsing session, temporarily pause a browsing session, enable retrieval, transmission, access, and/or display of only a portion of web content being requested by the user, and/or deploy another computing resource safeguard.

In this manner, the cloud browser may continuously detect and/or determine computing resource utilization of a browsing session. The cloud browser may determine when a threshold has been reached and/or exceeded, or is being approached, and then transmit a notification advising the user of the same.

In some embodiments, a browsing session may terminate after a period of inactivity. The cloud browser may continuously monitor for user input and/or user activity to determine whether the user is inactive. The duration of inactivity that triggers termination of a browsing session and/or one or more communication connections associated with a browsing session may be configurable by a user.

Third Party Integration

In accordance with embodiments described herein, the cloud browser may present web content to users in a more secure way than simply retrieving web content and displaying the web content on a user device. More particularly, the cloud browser may provide a multiplexed downstream view of the user. Multiplexed information may include a variety of files, objects, and/or other content such as images, videos, audio content, text, and/or the like. These different object types may be transcoded into a common format (e.g., an image display representation) so that they can be streamed to the user over a single communication connection. In some embodiments, a multi-channel protocol may transmit video and/or web page display information via one data path and/or protocol, and may transmit file objects (e.g. multimedia files, executable files, files operable to be natively executed on a user device) via a second data path and/or protocol. For example, file objects may be diverted through an organization's and/or third-party's pre-existing file analysis software stack in order to perform file analysis prior to download and/or upload (e.g. to filter for malicious, proprietary, and/or offensive content). In some embodiments, a cloud browser application and/or cloud browser environment may provide an API to an organization and/or third party for facilitating file object transmission during a cloud browser session. In some embodiments, a third party may refer to an organization and/or an entity not associated with a cloud browser application provider and/or cloud browser environment. In some embodiments a computing device (e.g. a server) for processing a file portion may be located at an organization, associated with an organization, co-located with a computing device (e.g. a server) executing a remote cloud browsing session, and/or associated with a remote cloud browsing session.

As stated above and below, the cloud browser may utilize a secure web container, a siloed computing device and/or server located remotely to the user device (e.g., secure web container 106 of FIGS. 1A and 1B), may retrieve and render web content. By rendering web content at an arm's length from the user device, the user device itself is not exposed to potentially harmful files and/or other web content. The cloud browser may also utilize a secure analysis application (e.g., secure analysis application 104 of FIGS. 1A and 1B) running on the user device to provide the user with a downstream view of the web content rendered at the secure location.

Using the cloud browser, the user may view the rendered web content over an encrypted communication connection between the user device and the secure web container. The cloud browser may generate one or more image files of the web content rendered at the secure web container. Instead of sending the actual rendered web content to the user device for display, the cloud browser may transmit generated image files of the web content to the user device. In this manner, and in accordance with various embodiments described herein, the cloud browser may provide a layer of security beyond mere browser isolation.

In some browsing sessions, a user may desire to download content directly onto his user device, or upload content from his user device. Policy controls may enable an administrator to authorize individual users and/or groups of users for downloading and/or uploading of content. This authorization may be provided on a per-person, per-project, per-session, per-organization, and/or temporal basis.

For example, the user may request to download a file included in web content that is rendered at the secure web container. In some embodiments, the request may include a selection of the file, and/or any other user input. In response to receiving a request to download a file at the user device, the cloud browser may determine whether the user is authorized to download the content. Authorization may be provided based on a user status as described above, a content type, a time and/or a day, device characteristics, and/or any other administrative policy. Determining whether the user is authorized may include comparing identification information received from the user device and associated with the user to a plurality of identification records stored in an identification database and determining whether there is a match between the identification information and an identification record in the identification database. The identification information may be associated with the user, the user device, a cloud browser, a browsing session, and/or the like. The cloud browser may access and/or communicate with one or more policy databases and/or identification databases comprising a blacklist of unauthorized users and/or devices, a whitelist of authorized users and/or devices, and/or the like.

After determining the user is authorized to download content (e.g., a file, a video and/or file object, text, an image, and/or the like), the cloud browser may transmit the desired content from the secure web container and/or a web server to the user device. Upon receipt, the user may then download and/or save the content directly to the user device and/or another storage medium.

Because the cloud browser may transmit only an image representation of web content to the user on the user device, and may not actually transmit the web content itself to the user device, content that is to be downloaded at a user device may be separated from the transcoded image representations of web content. In some embodiments, the content to be downloaded may be transmitted on a different communication connection than the one between the secure analysis application running on the user device and the secure web container and/or web server. The cloud browser may establish a second communication connection for this content download. In other embodiments, the content to be downloaded may be transmitted on the same encrypted communication connection between the secure analysis application running on the user device and the secure web container and/or web server.

In some embodiments, content that is to be downloaded to the user device (and/or otherwise may come into direct contact with the user device) may pass through a file analysis procedure. Passing a file through the file analysis procedure may occur prior to transmitting and/delivering the desired content to be downloaded, prior to downloading the content, and/or the like. The file analysis procedure may be deployed by the cloud browser at the secure web container and/or by the secure analysis application at the user device.

In some embodiments, the cloud browser may deploy the file analysis procedure using a processing device of the secure web container and/or the user device. During file analysis, the cloud browser may inspect the content to be downloaded for viruses, malware, ransomware, and/or other potential threats. Inspecting the content may include performing one or more scans of the content. If a potentially harmful object is identified based on a scan, the cloud browser may not transmit the desired content for download to the user device. If no potentially harmful object is identified, or if a potentially harmful object was identified but determined to not be harmful, then the cloud browser may proceed with transmitting the web content directly to the user device for download.

In other embodiments, the file analysis procedure may be operated by a third party device (e.g., a device not included in the secure web container and/or the user device). For example, the cloud browser may transmit the content from the secure web container and/or the web server to a third party processing unit. The cloud browser may include and/or utilize an API (e.g., API gateway 250 of FIGS. 2A and 2B) for routing the content to the third party processing unit. In this manner, the cloud browser may integrate seamlessly with existing document scanning and/or malware detection programs. Additionally, the file inspection procedures disclosed herein may occur remotely to the user device so that the user device remains unaffected by any potentially harmful files and/or objects. In some embodiments, inspection of files and/or software may be referred to as a “forked” integration, third-party file inspection, off-site file inspection, file analysis malware detection (e.g. for downloading content), and/or confidential, proprietary, objectionable, and/or offensive content detection (e.g. for uploading content).

The third party processing unit may include any of the computing elements, units, and/or subunits described herein, particularly with reference to FIGS. 2A and 2B. Once the web content to be downloaded has been received, the third party processing unit may inspect, scan, and/or otherwise analyze the content for potentially harmful artifacts (e.g., viruses, malware, threats, and/or the like). The third party processing unit may or may not identify one or more harmful artifacts in the content. If the third party processing unit does not identify any potentially harmful artifacts, then the third party processing unit may transmit a signal acknowledging the same. The cloud browser may then transmit the content directly to the user device for download. If the third party processing unit does identify a potentially harmful artifact, then the third party processing unit may transmit a signal acknowledging the same. If the third party processing unit determines the identified potentially harmful artifact is not harmful, then the cloud browser may then transmit the content directly to the user device for download. Alternatively, if the third party processing unit identifies a potentially harmful artifact that is actually potentially harmful, then the third party processing unit may transmit a signal acknowledging the same. In that case, the cloud browser may not transmit the content to the user device for download.

Upon determining content is potentially harmful to the user device, the cloud browser and/or the third party processing unit may add a record associated with the detected artifact to a database of known harmful artifacts. This database may be referenced by comparison and/or matching processes when determining whether an identified artifact is potentially harmful.

Content determined to not be potentially harmful may be received at the user device. The user may then download the content directly to the user device and/or in another storage location. Contrasted with the encrypted image representation delivery method, content for download is provided to the user device in its original form.

Similar processes as those described above for downloading content may be deployed for uploading content as well. For example, if a user wishes to upload content, the cloud browser may utilize third party scanning software to determine whether the content to be uploaded contains confidential, proprietary, and/or other sensitive information. This process may also be performed independently by the cloud browser. If the content to be uploaded contains confidential, proprietary, and/or other sensitive information, the cloud browser may prevent the content from being uploaded. Conversely, if the content to be uploaded does not contain confidential, proprietary, and/or other sensitive information, the cloud browser may permit the content to be uploaded. Similar processes as those described above for downloading content may also be deployed for tracking, logging, and/or storing content. Scanning and/or inspecting a file may occur based on an identified file type of the file.

Accessibility from Anywhere

A user may wish to access web content from a variety of device types with different operating systems, including multiple devices simultaneously, such as a mobile device, a laptop, a desktop, and/or the like. Accordingly, the cloud browser described herein may integrate with a plurality of devices. For example, the cloud browser may utilize a first secure analysis application (e.g., secure analysis application 104 of FIGS. 1A and 1B) specifically tailored to a user device of a first type (e.g., a mobile device) as well as a second secure analysis application (e.g., secure analysis application 104 of FIGS. 1A and 1B) specifically tailored to a user device of a second type (e.g., a desktop computer). In other embodiments, the cloud browser may utilize a common secure analysis application that functions across a plurality of devices.

In some embodiments, one or more users may utilize a plurality of devices to access a common secure web container. Because the cloud browser may store user credentials for a user, the user may be enabled to access a common web browsing session across multiple devices. In some embodiments, the user may access web content rendered at a secure web container across multiple devices (e.g., switch devices of different device types) without terminating the web browsing session. The cloud browser may establish encrypted communication connections between the secure web container and a plurality of devices for the transmission of image representations of web content rendered at the secure web container to each of the devices.

In some embodiments, a first secure analysis application running on a user device of a first type may emulate a second secure analysis application and/or other applications running on a second device (e.g., a second user device of a second type, an application hosting server, and/or the like). In some embodiments, running the secure analysis application on a particular device type (e.g., a mobile device) may include virtualizing one or more mobile applications and/or other applications native to devices of that device type. In this manner, the secure analysis application may enable a user of a particular device type to utilize features native to that device type without exposing the user's user device to potential harms. In some embodiments, virtualization and/or remote execution of content and/or software related to a cloud browsing session may enable seamless device switching across one or more computing devices. Devices accessing, executing, and/or interacting with a cloud browser may not need to be associated with a VPN or trusted network in order to receive full access to web content. For example two or more different computing devices may access and interact with a common (e.g. cloud) browsing session, even though the two or more different computing devices may have different input/output (I/O) capabilities, screen dimensions, geographic location, network connectivity, and/or underlying software (e.g. open source mobile device operating system, closed source desktop operating system).

In some embodiments, virtualization, sandboxing, and/or remote execution of any application (e.g. native mobile application, desktop application) may be performed by a remote computing device (e.g. a server), which may provide the same benefits to a user and/or user device as virtualization and/or remote execution of content and/or software associated with a cloud browsing session (e.g. less security risks for a user device, lower processing usage of a user device, facilitation of regionalized data storage, seamless device switching). Therefore, a remote computing device may perform “cloud streaming”, which may comprise one-way and/or two-way data streaming between a remote computing device (e.g. server) and a user device (e.g. smart phone). In some embodiments, an emulated multi-tenant mobile environment may stream applications (e.g. mobile applications) and/or interaction data thereof during, within, and/or separate from a secure browsing session. In some embodiments, data and/or software may be executed remotely for one or more applications by a server farm and/or virtualized mobile application farm. In some embodiments, native mobile application code corresponding to a mobile application may be replaced with and/or redirect to native mobile device code operable to stream and/or interact with a cloud server and/or remote computing device.

In some embodiments, the user device may communicate with and/or receive information from a secure web container that provides functionality of the same device type as the user device. Said another way, the user may utilize the secure analysis application on a user device to access a secure web container running software, an application, and/or the like that is compatible with the user device. In some embodiments, utilizing the secure analysis application may include triggering a secure web container to download and/or run a second application in the secure web container for use by the user. The cloud browser may identify one or more applications native to the user's user device, and then initiate a secure web container with the identified one or more applications. The applications running at the secure web container may be streamed to the user device in such a way as to provide the user with a display representation (e.g., image files) of web content as opposed to transmitting the original web content to the user device.

In some embodiments, multiple user devices (e.g. smartphone, tablet, personal computer) may access the same cloud browsing session simultaneously and/or serially. For example, a remote cloud browsing session may be initiated upon a first request for Internet content from a user device, or may be initiated before a request for Internet content (e.g. the remote cloud browsing session may be executing in a waiting, background, and/or dormant state until a request for Internet content is received). One or more devices may then simultaneously establish a connection with the remote cloud browsing session by sending requests for Internet content and/or receiving transmissions of second Internet content based on the requested internet content (e.g. the second Internet content may be an image representation of the requested Internet content and/or a subset of the requested Internet content). Alternatively or additionally, a remote cloud browsing session may transmit the second Internet content to more than one device simultaneously (e.g. a second user device could request to monitor and/or receive a duplicate of the transactions with a first user device requesting Internet content from the remote cloud browsing session). In some embodiments, a first user device may begin a remote cloud browsing session and a second user device may end a remote cloud browsing session. Additionally or alternatively, a remote cloud browsing session may service more than one user device at substantially the same time.

Upon starting a web browsing session, the cloud browser may identify a device type of the user device. The cloud browser may then select a secure web container of the same type and/or a type that is otherwise compatible with the user device. The secure web container may include an emulator and/or a virtual machine that is accessed as described herein by the user device. During the web browsing session, information rendered at the secure web container may be displayed on the user device using one or more transcoding protocols. In some embodiments, and as described above and below, the transcoding protocols used may include instructions for generating and/or displaying image representations of web content. The transcoding protocols may also include a specific frame rate, sample rate, display characteristics, and/or the like for generating image representations. In some embodiments, image representations may include auditory representations (e.g., samples of audio content). These audio files may be screened for potentially harmful artifacts just like an image, a video, text, and/or other files would be.

As described herein, the cloud browser may utilize one or more secure web containers during a browsing session. In some embodiments, a first secure web container may be dedicated to operating and/or processing in accordance with a first type of device (e.g., mobile devices), whereas a second secure web container may be dedicated to operating and/or processing in accordance with a second type of device (e.g., laptops). Multiple secure web containers utilized in a common web browsing session may communicate with each other to provide a substantially seamless web browsing experience across multiple devices. Depending on the device type from which a request for web content is received, the cloud browser may direct a particular secure web container to retrieve, process, and/or present web content for display at the user device. In some embodiments, a device type may include an operating system type.

Compliance with Regulations

The cloud browser as described herein may fully comply with governmental regulations across the world, especially those related to data privacy (e.g., General Data Protection Regulation (GDPR)). For example, an administrative portal may enable an administrator to set policy controls governing the logging of browser data, the storage of user data, the separation of personal browsing data from work-related browsing data, the regionalization of data storage, and/or the like.

In some embodiments, the cloud browser may track one or more pieces of data associated with a browsing session and/or a user. For example, the cloud browser may store pieces of information such as an IP address of a user device, an IP address of a secure web container, an IP address of an egress node, an IP address of a web server, a masked and/or manipulated IP address, a device identification number, a user identification number, a browsing session number, a time and/or day of browsing session initiation and/or termination, personal information associated with a user, purchase information used during a web browsing session, user authentication credentials, an image of the user, a video of the user, a sound clip of the user, a website URL, an amount of computing resources utilized during a particular process, metadata associated with content, content, text, images, video, audio, files, documents, and/or malware, and/or any other piece of information associated with a user, web content, a device, a content file, and/or the like.

In some embodiments, tracking data includes tracking data across all mediums the data may contact throughout its life. For example, tracking data may include noting storage locations in which the data has been stored, devices that have processed the data, network nodes through which the data has been routed, and/or the like. The cloud browser may also store timestamps associated with receipt, retrieval, transmission, processing, storage, and/or any other operation performed by the cloud browser or a third party device external to the cloud browser.

In some embodiments, the cloud browser may store every piece of information relating to a browsing session. In some embodiments, the cloud browser may selectively store information of a first information type, file type, file size, and/or the like. Again, storage of information may be dictated based on policy controls in the administrator portal and/or in another menu location. A user may be enabled to toggle and/or select which pieces of data are being tracked and/or stored, as well as the method, location, and/or duration of storage. In some embodiments, the tracked and/or stored data may be referred to as a history or log of data. Histories and/or logs may be stored in a storage location so as to be accessible by one or more users at a later date. A cloud browser may simplify employee and/or user network activity recordation by an organization, institution, and/or entity. In some embodiments, interacting with a network (e.g. the Internet) through a cloud browser may provide a single portal that tracks and/or logs network activity (e.g. of a user). Further, a cloud browser may provide tools, functionality, features, and/or background processes that satisfy and/or facilitate compliance with a policy (e.g. regulatory policies such as GDPR). For example, a cloud browser may reduce and/or eliminate the need of an organization to log, manage, and comply with a policy regarding network activity (e.g. such as providing a user with a file and/or representation of logged data). Logged data may be stored locally (e.g. on a user device, on an organizational server) and/or at a remote location (e.g. on an organizational server, on a server executing and/or providing a cloud browser service).

The cloud browser may additionally include an option that enables a user to turn off this data tracking feature. As such, when the data tracking feature is turned off, the cloud browser may not store one or more pieces of information. With the data tracking feature turned off, no history or log of browsing and/or personal data may be created by the cloud browser. Turning off data tracking may be a feature accessible to some users, but not accessible to other users. This policy control may be set based on a user status, a user location, an organization type, and/or the like.

In some embodiments, only information obtained from certain sources (e.g., websites, devices, and/or the like) may be tracked and/or stored. Whitelists and/or blacklists may be utilized for governing which sources of content and/or information require tracking, logging, and/or storage.

To comply with regulations, the cloud browser may further generate, transmit, and/or present to the user a notification notifying the user of each piece of information and/or each category of information being stored. In some embodiments, the cloud browser may generate a report including a listing of all pieces of information being tracked and/or stored for a given browsing session. The cloud browser may also assign a purpose for which the data is being tracked, stored, and/or used to each piece of data, which may then be displayed in the report. A user of the cloud browser may request and/or obtain such a data tracking report on demand or at will. In some embodiments, the cloud browser may delete information after it has been requested by a user, after it has been stored for a predetermined period of time, and/or based on other policy controls. In this manner, the cloud browser may provide excellent audit logging and/or visibility. In some embodiments, a user may also request deletion of personal information, browsing data, and/or the like.

In some embodiments, a user and/or end user may specify and/or modify data tracking requirements and/or configurations. A cloud browser application and/or cloud browser session may notify a user (e.g. a user of the cloud browser session) of data and/or types of data being logged and/or stored (e.g. before, at the time of, and/or after such data is logged and/or stored), may notify a user of the purpose of data tracking and/or logging, may present a user an option to allow and/or disallow logging and/or storing of data (e.g. user-identifying information), and/or may require a user accept and/or approve of a data tracking and/or logging policy before tracking, logging, and/or storing data. In some embodiments, a cloud browser application may handle requests for accessing and/or deleting personal browsing data. In some embodiments, a cloud browser application may select and/or execute a “no log policy”, e.g. at the request of the user or without a user request, in which data associated with a cloud browsing session may not be tracked, logged, and/or stored by a user device, organization, and/or cloud browser application. Additionally or alternatively, in some embodiments, an encrypted log policy may be selected and/or executed. For example, data (e.g. user-identifying data) associated with a cloud browsing session may be encrypted based on a public key generated for (e.g. by the cloud browser) and/or provided by a user, administrator, organization, and/or third party. For example, an encrypted log policy may allow access based on organization status, user request, geographic location, regulatory (e.g. GDPR) compliance.

In some embodiments, a remote cloud browsing session may log data associated with a user device and/or remote cloud browsing session based on the state and/or configuration of a digital switch (e.g. a logging switch). A remote cloud browsing session may set the configuration of a digital switch and/or request a user device (or user and/or organization associated with the user device) to define the configuration of a digital switch. For example, a digital switch may comprise a setting on whether or not to log data, where to log data, what kind of data to log, when to log data, how much data to log, and/or how long to store logged data.

In some embodiments, the storage of web browsing session data and/or personal data may be regionalized. For example, web browsing data generated by a user located in a European country may be stored at a storage location located in that same European country. More broadly, data generated by a European user in any location around the world may be stored and/or logged in a European server location. For example, a European user may be traveling in Asia. While working in Asia, the European user may generate browsing data. Though the cloud browser may utilize one or more computing elements located in Asia to create and/or otherwise provide a secure cloud browsing experience, the data generated by the European user may still be stored and/or logged in a European storage location. At minimum, data generated in a first location may be stored at a storage location that is compliant with regulations. The cloud browser may identify, based on one or more policy controls, a storage location that is compliant with regulations. The storage location may be set at a global level, a national level, a regional level, a state level, a city level, a zip-code level, and/or the like by an administrator or user using the policy controls described herein. Storage of data may be regionalized to satisfy and/or facilitate regulatory (e.g. GDPR) compliance.

In some embodiments, a remote cloud browsing session may determine a user identity of a user associated with a user device, an organizational identity associated with a user device, and/or an organizational identity associated with an organizational network used by a user device. For example, a remote cloud browsing session may log data associated with the remote cloud browsing session and/or a user device in a certain (e.g. geographic and/or network) location based on a user identity and/or an organizational identity associated with the user device. Regionalized logging of data may be based on efficiency of data storage and/or retrieval, regulations, and/or logging preferences associated with the user device. For example, a user identity associated with a user device may comprise a nationality. Based on the nationality, the remote cloud browsing session may directly and/or indirectly (e.g. via computing instruction) determine an appropriate geographic and/or network storage location of data associated with the user device and the remote cloud browsing session. For example, the storage location of data associated with the user device and the remote cloud browsing session may be constant despite a user device being located in one or more countries during interaction with one or more remote cloud browsing sessions.

In some embodiments, the use of a cloud browser may facilitate regulatory compliance and/or regionalized storage of personal (e.g. user- and/or organization-identifying) data. For example, typical browser may require and/or default to client-side (e.g. at the user device) downloads of content (e.g., including user information). However, a cloud browser may allow and/or facilitate storage and/or downloading of content to jurisdictions and/or geographies compliant with regulations. The storage and/or downloading may be regionalized, e.g. based on user-identifying data, organization-identifying data, employee status, and/or user location.

In some embodiments, the tracking of data may include identifying a location (e.g., an IP address) of a device from which a request for initiation of a browsing session is received. Upon initializing the browsing session, the cloud browser may identify one or more storage locations for storing data that is to be tracked based on one or more policy controls. The cloud browser may receive a user selection of one or more pieces of information to be tracked and/or stored, excluded from tracking and/or storage, and/or the like. Data may be tracked and/or stored based on the received user inputs. In some embodiments, the cloud browser may store tracked data in a storage location comprised in the one or more compliant storage locations. The cloud browser may also determine which storage location is most efficient for storage based on location, computing resources, and/or the like.

In some embodiments, the data being tracked and/or stored may be received by the cloud browser and/or one or more computing elements described herein from a user device, a secure web container, an egress node, a web server, a storage location, a third party processor, and/or any other device. The cloud browser may encrypt received information as it is being tracked and/or stored for security purposes.

In some embodiments, the cloud browser may separate different types of data for different processing and/or storage. For example, the cloud browser may separate personal information and/or personal browsing session data from work-related browsing session data. In some embodiments, the cloud browser may identify a source (e.g., a URL from which data and/or content was obtained, a device identification, and/or the like) of received data, and based on the source, determine a type for the data. Determining the type for the data may include assigning a tag to the data, wherein the tag directs the cloud browser to process, track, and/or store the data in a particular way. For example, personal contact information may not be stored by the cloud browser, whereas personal browsing session data may be temporarily stored, and work-related browsing session data may be permanently stored.

In some embodiments, users associated with the cloud browser (e.g., administrators, product developers, database maintenance workers, and/or the like) may have access to only a portion of stored browsing session and/or person data. As such, some data that is tracked and/or stored by the cloud browser may remain private to the user and/or organization associated with the user that generated the data (e.g., an employer and/or client), being accessible only to the user and/or his organization. For example, a password may be required for accessing particular pieces of information being tracked and/or stored by the cloud browser, where the password is known only to the user and/or organization responsible for generating the information. In some embodiments, the cloud browser may designate particular storage locations for certain users, organizations, and/or projects based on one or more policy controls. Alternatively or additionally, in some embodiments, access to stored and/or downloaded data (e.g. by a user, administrator, organization, and/or third party) may be limited and/or prevented based on user-identifying data, organization-identifying data, employee status, and/or user location. In some embodiments, a hierarchical rule-based system may be employed, with access privileges specified and/or modified by an administrator. Such a hierarchical rule-based system may be employed in conjunction with a cloud browser application and/or session. In some embodiments, data may be accessible using public key encryption. In some embodiments, the cloud browser may be used for all personal browsing sessions, whereas a second browser may be used for work-related browsing sessions. In this manner, data privacy may be maximized.

In some embodiments, consent may be required for data to be tracked and/or stored. The cloud browser may request authorization for tracking, logging, and/or storing one or more pieces of information. Upon receiving consent from the user and/or organizational administrator, the cloud browser may proceed with tracking, logging, and/or storing browsing session data and/or other information. If consent is not provided, the cloud browser may not track and/or store at least a portion of incoming data.

As briefly mentioned above, the cloud browser may enable the user to request and/or obtain a list of information pieces being tracked, logged, and/or stored with ease. The user may also be enabled to quickly request, delete, and/or obtain the actual information that is being or already has been tracked, logged, and/or stored. In response to receiving a request for browsing session data and/or personal information, the cloud browser may transmit a copy of the requested information to the user device and/or another device (e.g., a publicly-accessible server). Alternatively, the cloud browser may transmit the original information from a storage location to the user device and/or another device. Upon transmitting the requested information, the cloud browser may delete one or more records associated with the requested information. In some embodiments, all records associated with the requested information may be deleted. In some embodiments, transmitting the requested information includes transforming the requested information into a consumable data format.
